Specification of Letters Patent.

Application iled May 17,1906. Serial No. 317,336.

To @ZZ-whom t muy concern:

Be it known that 1, FERDINAND HAss, a citizen of the United States oi' America, residing at 4 Mansiield road, Ilford, Essex, England, have invented certain new and useful Improvements in Trolleys, Hand-Trucks, and the Likeof which the following is a specification.

The object of this invention is to construct trolleys, hand-trucks, and the like having two wheels with a movable frame or under carriage carrying the axle and wheels in such manner that said trame and wheels can be caused to alter their position under the trolley or truck, so asv to form a movable or adjustable ulcrum for the purpose of raising a load onto the trolley or truck in a more easy manner than with the present construction 'of trolley or truck.

My invention is illustrated in the annexed drawings as applied to an ordinary trolley, Figure 1 being a view of the under side o-f the trolley; Fig. 2, a side view with a detached plan viewf` of the lever used for raising the edge of va heavy case or the like for the shoe of the trolley to be pushed under it. Fig. 3 is a side view of the trolley as in use. Figs. 4 and 5 are detail side elevations of a iixed rack on the body oi' the trolley engaged by a pivoted toothed sector on a movable frame, as at Fig. 4, or disengaged, as at Fig. 5. Figs. 6, 7, and 8 are detail iront elevations, respectively, on a hollow block or guide on the movable frame, the` iixed rack on the body, and the pivoted sector; and Figs. 9, 10, 11 are side elevations of Figs. 6, 7, and 8, respectively.

For the purpose of my invention, I mount the axle 1 and wheels 2 of the trolley or truck on an independent frame or carriage 3, which is so formed as to be slidable under the body proper, 4, of the trolley or truck. Upon the bars 5 of this movable or sliding frame 3 is a hollow block or guide-piece 6, (see Figs. 1, 6, and 9,) serving as a guide for a rack 7, attached to cross-bars 8 3 of the'body proper, so that the hollow block or guide 6 may travel along the 'rack 7 and carry with it the movable frame 3 and the wheels 2, so as to alter the position of the fulcrum.

The movable frame 3 is locked in the desired position by means of a toothed sector 9, pivoted in bearings 10 of the hollow block or guide-piece 6 and carrying a depending arm 11 and treadle-piece 12, this toothed sector 9 being pivoted at a point out of its center line, as shown, (see Figs. 4 and 5,) in such a manner that its teeth are normally in engagement with the rack 7 on the trolley-body; but by moving the depending arm 11 of the sector 9 by pressing the foot on the treadlepiece 12 or otherwise the sector 9 may be swung out of engagement with the rack 7 on the body ofthe trolley, thus permitting the movable frame 3 to slide freely under the' trolley. l

13 13 are small wheels or rollers fitted to the end of the trolley, which come into action when the trolley is to be wheeled onto a higher level, such as in getting over a step. In this case the movable frame 3 is allowed to slide back, as at Fig. 3, thus leaving the end of the trolley proper projecting beyond its liulcrum-wheels, whereby the rollers 13 13 can be pushed onto the higher level or step and 4form a temporary fulcrum until the wheels 2 rest upon the higher level and support the load thereon.

14 is a lever or crowbar which when not in use is supported in the holders or rests 15 16. This lever is employed for assisting in raising the edge of a heavy load to enable the shoe 17 of the trolley to be pushed under it. This is done by passing the lever through the bearing 18 in such manner that its iianges 19 rest within the ledges of the bearing or fulcrum 17 and so that its claw 20 can be prized under the case or load to be lifted by working the handle end of the lever.

By this invention a great saving of labor or exertion is effected, as when it is required to place a heavy or bulky load, such as a packing-case or large piece of furniture, onto the trolley all that is necessary is to push the shoe 17 of the trolley under the load in the usual manner, then with the Jfoot to move the pivoted sector 9 out of engagement with the rack 7, so as to allow the movable frame 3, carrying the wheels 2, to travel backward toward the handles 21 of the trolley, so as to shift the fulcrum and require less exertion in tilting the trolley to raise the load and balance it on the trolley. The movable frame 3 can then be locked in that position, if desired, by releasing the treadleearm 11 oi' the toothed'sector 9, so that the latter falls into engagement With the rack 7.

IOO

What I claim, and desire to secure by Letters Patent, is- I 1. 1n trolleys, hand-trucks, and the like, the combination of body-frame 4 iitted with rack 7, slidable underframe 3 carrying the IIO axle 1 and Wheels 2, and itted with guideblock 6 carrying pivoted sector 9 engaging said rack 7 on the` body-frame 4, substantially A in the manner speciiied and for the purpose set forth.

2. In trolleys, hand-trucks, and the like, the combination of trolley-frame 4, rack 7, slidable underframe 3 carrying aXle l and Wheels 2, guide-block 6 on said underframe and carrying pivoted sector 9, bearing 18, lever 14,k and rollers 13 on frame 4, substantially as described.

3. In trolleys, hand-trucks and the like having a frame itted With a rack, a Slidable under carriage having Wheels, a guide-block, and sector eccentrically pivoted on said block and engaging said rack on the frame.

4. In trolleys, hand-trucks and the like having a frame provided With a rack, the Y f," F. C. SMITH.

combination of an under carriage having Wheels, bars on said carriage, a guide-block mounted on said bars and carrying a pivoted sector engaging said rack on the frame.

5. In trolleys, hand-trucks and the like having a frame tted With a rack, a slidable under carriage having Wheels, a guide-block, a sector pivoted on said block adapted to engage said rack on the frame, and a treadle portion formed integral With said sector.

6. In trolleys, hand-trucks and the like, a

Aframe having a shoe, a bearing located adj acent to said shoe, and a lever for removably engaging said bearing.

In testimony whereof I have hereunto set my hand in presence of tvvo subscribing Witnesses.
